Product Description
High absorption 4A molecular sieve desiccant granules
Molecular Sieve type 4A (Angstrom) is an alkali alumino silicate, obtained through synthesis of type A zeolite in sodic form.
It is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm).
Galaxychem type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
Typical Chemical Formula
Na2O . Al2O3 . 2SiO2 . 4.5 H2O
